techSetLxExtractLayer

techSetLxExtractLayer(
d_techFileID 
tx_extractLayer
)
=> t / nil

Description

Adds the specified layer to the list of extract layers in the virtuosoDefaultExtractorSetup constraint group in the specified technology file. The extract layers are listed under validLayers in the interconnect subsection of the constraint group. If any of the necessary technology file sections do not already exist, this function creates them.

Arguments

d_techFileID	Database ID of the technology file.
l_extractLayers	Layer name or number.

To optimize performance, specify only the name of each layer to extract, not the layer name and layer purpose. If you specify a purpose, it is ignored.

Value Returned

`t`	The specified layer was added.
`nil`	The technology file does not exist, the constraint group is not in the technology file, or the constraint group does not list any valid layers.

Example

techSetLxExtractLayer( techFileID "metal1" )

Adds the metal1 layer to the list of extract layers in the virtuosoDefaultExtractorSetup constraint group in the technology file identified by techFileID.
